- Abstract
- This paper presents the effects of height and coverage density of diffusive surfaces through the measurements of scattering and diffusion coefficients using scale models. Measurements were conducted using a 1:10 scale model. Scattering coefficients of 1D, 2D, and 3D diffuser profiles as well as diffusion coefficients of the 3D diffuser profile (hemisphere) were measured. It was found that the structural height of the diffuser is closely related to the frequency characteristics of the scattering coefficients, while the coverage density of the diffuser is closely related to the values of the scattering coefficients. Diffusion coefficients were less sensitive to structural height and coverage density than were the scattering coefficients. Using the measurement results, scattering and diffusion coefficients were estimated. In addition, the relationship between scattering and absorption coefficients was discussed.
